7 Claims. (Cl. 229- 54) This invention relates to bags, and moreparticularly to handled sewn multiwall paper bags.

Among the several objects of the invention may be noted the provision inan economical manner of a sewnbag, and particularly a sewn multiwallpaper bag, with a handle by means of which the filled bag may beconveniently carried without discomfort to the hand; the provision ofsuch a bag with a handle which is in itself strong and which is firmlyattached to the bag so that it will not rupture or tear loose from thebag under a relatively heavy load; the provision of such a bag with ahandle which occupies an out-of-the-way position until it is to be usedfor carrying the bag; and the provision of such a bag with a handlewhich is attached to the bag as an incident to the formation of theclosure of one end of the bag. Other objects and features will be inpart apparent and in part pointed out hereinafter.

The invention accordingly comprises the constructions hereinafterdescribed, the scope of the invention being indicated in the followingclaims.

In the accompanying drawings, in which several of various possibleembodiments of the invention are illustrated:

Fig. 1 is a view in elevation of a sewn paper bag provided at the topwith a handle of this invention;

Fig. 2 is an enlarged cross section taken on line 2-2 of Fig, l,thicknesses being exaggerated;

Fig. 3 is an enlarged cross section taken on line 3-3 of Fig. 1,thicknesses being exaggerated;

Fig. 4 is a view illustrating the formation of the handle per se; and,

Fig. 5 is a view illustrating a modification.

Corresponding reference characters indicate corresponding partsthroughout the several views of the drawmgs.

Referring to the drawings, there is indicated at 1 a paper bag providedwith a handle 3 of this invention. The bag would usually be a multiwallpaper bag (a plural-ply paper bag), but it will be understood that thehandle is applicable to a single-ply paper bag, or to a bag made ofmaterial other than paper. One end of the bag (the upper end as shown inFig. l) is closed by a sewn closure generally designated 5, including apaper tape 7 folded around the end of the bag, a filler cord 9 and aline of stitching 11 driven through the filler cord,

the tape and the bag walls to hold the walls together and to hold thetape in place. Tape 7 may or may not e pasted to the bag walls. Theother end of the bag (its lower end as shown in Fig, 1) may be initiallyleft open, being subsequently closed after the bag has been filled as bymeans of a conventional stitched closure. It is also possible that thebag might be a valve bag, in which case both ends of the bag would beinitially closed.

As shown, the stitching 11 comprises a needle thread 13 having loops 15extending from one side of the bag (which is referred to as the needleside) through the filler cord 9, the tape 7 and the bag walls, and alooper thread 17 on the other side securing the loops 15 from 2,957,618Patented Oct. 25, 1960 being pulled out. It will be understood that thestitching may be of the conventional chain stitch or lock stitch type.It may be a single-thread type of stitching instead of a two-threadtype. The tape 7 projects beyond the sides of the bag, and the stitching11 extends in a straight line throughoutthe length of the tape.

The handle 3 consists of a strip of narrow woven textile fabric, such asa coarse plain-woven cotton fabric of a type such as is used fordrawtapes in drawtape bags (see, for example, Scruggs US. Patent2,557,517, dated I June l9, 1951). The handle'strip 3 has a lengthsomewhat greater than-the width of the bag, and somewhat greater thanthe length of the closure tape 7. The width of the material of thehandle strip may be approximately two inches, for example. It is bunchedor pleated by folding it along longitudinal fold lines as indicated at19 in Fig, 4. End portions 3a of the'bunched or pleated strip 3;aredisposed under the closure tape 7 on one side of the bag(the needleside) and are caught in the stitching. 11. The strip 3 extends fromend-to-end of the tape 7 and the ends .of the strip .are coincident withthe ends of the tape. As stated, the strip 3 is longer than the tape,:7,and it:has a loose central portion 3b free of the stitching, 11. andlocated out from under the tape 7 which is adapted to be grasped in thehand for carrying the bag, then assuming a position such as illustratedin dash lines in Fig. 1.

With the bunched or pleated end portions 3a of the strip 3 caught institching 11 under tape 7, the strip is securely caught and will notreadily tear out from the stitching, even under a relatively heavy load.Also, the bunched or pleated end portions are of substantial breadth sothat there is no particular difiiculty in assuring registration thereofwith the needle of the sewing machine during the stitching operation,even though the bunched end portions are under the tape 7. The stripitself is strong so that it will not break even under a relatively heavyload. The bunched or pleated central portion 3b which is grasped in thehand is of such character that it does not cut into the fingers, so thatthe filled bag may be comfortably carried.

Fig. 5 illustrates a modification involving the stitching of the foldedhandle strip 3 as indicated at 19, the stitching running longitudinallyof the handle strip 3 throughout its length. This strengthens the strip.The strip is initally folded along its longitudinal center line asindicated at 21, and the stitching is spaced from the fold and maintainsthe strip in its folded condition;

If necessary or desirable to strengthen the sewn end of the bag, areinforcing band such as shown in Williams US. Patent 2,854,186, datedSeptember 30, 1958, may be used.

In view of the above, it will be seen that the several objects of theinvention are achieved and other advantageous results attained.

As various changes could be made in the above constructions withoutdeparting from the scope of the invention, it is intended that allmatter contained in the above description or shown in the accompanyingdrawings shall be interpreted as illustrative and not in a limitingsense.

I claim:

1. A bag having a closure at one end constituted by a tape folded overthe end of the bag and a line of stitching driven through the tape andthe bag walls, and a handle at said end of the bag constituted by astrip of material having bunched end portions underlying the tape on oneside of the bag and caught by the stitching and having a loose centralportion free of the stitching and located out from under the tape andadapted to be ing a reinforcement extending lengthwise thereof.

2. A bag having a closure at one end constituted by a tape folded overthe end of'the bag and a line of stitching driven through the tape andthe bag'walls, and a handle at said end of the bag constituted by astripof material extending from end-to-end of the tape with its endscoincident with the ends of the tape, said strip having bunched endportions underlying the end portions of the tape on one side of the bagand caught by the stitching and having a loose central portion free ofthe stitch ing and located out from under the tape and adapted to begrasped in the hand for carrying the bag.
